How BA858 actually runs

Pro Flight Search has tracked every published board update for BA858 across the LHR and PRG boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left heavily delayed (~47 min) but landed a little late (~7 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how BA858 operates rather than what the timetable promises. Numbers refresh as new flights operate.
